title: 2,5-Bis[4-methyl-3-(pyridin-3-yl)phenyl]-1,3,4-oxadiazole and its one-dimensional polymeric complex with ZnCl2.
abstract: 2,5-Bis[4-methyl-3-(pyridin-3-yl)phenyl]-1,3,4-oxadiazole (L), C26H20N4O, forms one-dimensional chains via two types of intermolecular π-π interactions. In catena-poly[[dichloridozinc(II)]-μ-2,5-bis[4-methyl-3-(pyridin-3-yl)phenyl]-1,3,4-oxadiazole], [ZnCl2(C26H20N4O)]n, synthesized by the combination of L with ZnCl2, the Zn(II) centres are coordinated by two Cl atoms and two N atoms from two L ligands. [ZnCl2L]n forms one-dimensional P (plus) and M (minus) helical chains, where the L ligand has different directions of twist. The helical chains stack together via interchain π-π and C-H···π interactions.
